[Keyboard] Planck Layout Macro Refactor, Part II (#6156)

* Move layout macros to revision folders

* Update Planck EZ layout macros

Planck EZ only supports one layout (centered 2u spacebar). Deleted all the other macros.

* Flesh out QMK Configurator support

Give each Planck revision its own info.json file.

* Readme updates

- give each revision its own readme
- add the Planck EZ to the main Planck readme

* Fix layout macro for Planck EZ

Previous matrix didn't compile because the electrical matrix defined a k3b location, which was unused by the physical arguments.

Drashna was kind enough to confirm the Planck EZ's matrix for me.

* Pretend the Planck EZ supports ortho_4x12 layout

The hardware doesn't, but doing so prevents CI errors because the default keymap uses LAYOUT_planck_grid.

Going to pretend LAYOUT_ortho_4x12 is a valid layout for the Planck EZ.

* Update Planck EZ's URL in info.json
